Just came from the range. I have been working up a buffalo load for my 15 year old for an up coming hunt in Zim in two weeks. Used 71 gr. RL 15, 300 gr. TSX, and Federal 215 M primers. We got 2495 fps. average. But the best part was that all groups were 1 1/8" or less and the best group(him shooting) was .36" ! I think we have our load.
